100% RoHS compliant
Low TCR options: 30, 50, 100, 200 ppm/°C
What is the URH 20W to 100W UL Metal Clad Resistor?
The URH is a UL-recognized, aluminium-housed, chassis-mounted metal clad resistor rated from 20W to 100W. With a resistance range of 0.1Ω to 50kΩ, tolerances of ±1%, ±2%, or ±5%, and low TCR options (30, 50, 100, 200 ppm/°C), it is fully RoHS compliant and suited for applications requiring UL approval in industrial control panels, power conversion systems, and high-reliability equipment.
